Present Scenario Of Polyhouse Farming In Haryana
Author:Promila Dahiya And Kiran Singh1
Volume: 8 | Issue no: 1-2017 | Pagination: 109-116
Agriculture has played and will continue to play a dominant role in the growth of Indian economy in the foreseeable future. It represents the largest sector producing around 28 per cent of the GDP, is the largest employer providing more than 60 per cent of the jobs and is the prime arbiter of living standards for seventy per cent of India?s population living in the rural areas. In some of the temperate regions where the climatic conditions are extremely adverse and no crops can be grown, man has developed methods of growing some high value crop continuously by providing protection from the excessive cold, which is called as polyhouse technology. With the polyhouse technology, farmers can grow almost any fruits, ornamentals and vegetables in any season. This technology has made possible to have all vegetables throughout the year. According to study, in Haryana state 620 different types of polyhouses were found including 7-Hi-Tech, 50-WIT, 106-AINSH and 457-NVPH. The total number of polyhouses in Haryana are 614 with covered area of 17,57,920 m2. In Haryana, 1,956 people were found to be engaged in polyhouse farming.

Author:Insaf Khan, Devendra Singh1 And Bhanwar Lal Jat2
Volume: 8 | Issue no: 1-2017 | Pagination: 99-108
The present study was elucidated the effects of biofertilizers on plant growth and yield characters of Pisum sativum L. The research was conducted during Rabi 2016-2017 at the field experimentation centre of the Department of Agronomy, Bhagwant University Ajmer, during the year of 2016-2017. The data were recorded on 11 characters. Based on the mean performance the treatment- 8 (100% RDF + Rhizobium 30g/kg) was found best treatment for plant growth and seed yield. This obtained high in plant height (cm), number of primary branches per plant, number of leaves per plant, days to 50 per cent flowering, number of pods per plant, days to maturity, pod length (cm), number of seed per pod, seed index, seed yield per plant, nodules per plant. Interaction effect of biofertilizers was significant for all characters. Thus, it indicates that the process of biofertilizers may be better option for seed growers to achieve seed yield and yield components in pea.

Volume: 8 | Issue no: 1-2017 | Pagination: 89-94
An experiment was conducted to evaluate the effect of irrigation and nutrient scheduling on the yield and economics of bell pepper (Capsicum annuum L.) under protected structure during 2014 and 2015 at Calicut village, Andaman and Nicobar Islands. Four regimes of irrigation based on IW/CPE ratio (I1-0.25; I2-0.50; I3- 0.75 and I4-1.0) and nutrient levels consisted of five different composition of fertilizers to supplement the nutrient requirement of crop was used to find out the best treatment (N1-100% recommended dose of NPK (inorganic form); N2-50% of inorganic NPK + 50% organic manure; N3- 75% of inorganic NPK + 25% organic manure; N4-25% of inorganic NPK + 75% organic manure; N5-100% organic manure). Combined variance analysis indicated that experimental seasons were not significantly different, but irrigation intervals and nutrient level both significantly influenced the performance and the total capsicum yield. Highest yield was recorded from the combination of irrigationat 0.75 IW/ CPE ratio and nutrient application of 100 per cent recommended dose of NPK (inorganic form) (I3N1) treatments at par with the treatment of irrigation at 1.0 IW/CPE ratio and nutrient application of 100 per cent recommended dose of NPK (I4N1). However, with the lower irrigation frequency (I1), lower yields were obtained with all nutrient levels. Both I and N significantly influenced the fruit weight, number of fruits per plant branches, quality of fruit and the total yield. The cost benefit ratio of 2.2:1 was recorded in the I3N1 (irrigationat 0.75 IW/CPE ratio and nutrient application of 100% recommended dose of NPK). Therefore, the conclusion, I3N1treatment is recommended for naturally ventilated polyhouse grown bell pepper in this Island ecosystem in order to attain higher yields with improved quality.

Author:Imtiyaz Ahmad Lone
Volume: 8 | Issue no: 1-2017 | Pagination: 84-88
The present investigation on diversity for kernel colour in the natural population of walnut (Juglans regia L.) in the Kashmir valley was carried out in order to document the available genetic variability in walnut germplasm and to select elite walnut genotypes possessing superior attributes and quality traits. During the survey, data was recorded on one hundred fifty two (152) walnut trees growing in different areas of Kashmir valley. Remarkable variability was observed in seedling walnut trees for different morphological, nut and kernel characters. Similarly, variations were also reported for other characters viz., tree vigour, growth habit, branching habit, leaflet shape, shoot colour, nut shape, shell texture, shell colour, shell seal, shell strength, shell integrity, kernel shrivel and kernel colour. Kernel colour in the present study varied from extra light to amber. Twenty four genotypes (15.79%) were having extra light coloured kernels; 100 genotypes (65.79%) were found to have light coloured kernels; 18 genotypes (11.85%) had light amber coloured kernels and remaining 10 genotypes (6.57%) had amber kernel colour.

Author:Harphool Meena, P. K. P. Meena1 Andb. L. Kumhar1
Volume: 8 | Issue no: 1-2017 | Pagination: 80-83
An experiment was conducted at Agricultural Research Station, Borwat Farm, Banswara during Kharif -2010 and 2011 to find out optimum pant geometry and fertility levels for Bt cotton hybrid under three plant geometries (90 x 90, 90 x 60 and 90 x 45 cm) and three fertility levels (i.e. 75, 100 and 125 % RDF). Significantly higher seed cotton yield was recorded (2301 kg ha-1) under closer geometry of 90 x 45 cm (2301 kg ha-1) than wider plant geometry of 90 x 60 cm (1934 kg ha-1) and 90 x 90 cm (1759 kg ha-1), respectively. Though, yield attributing parameters such as bolls plant-1 and boll weight were statically improved in wider as compared to closer spacing but it could not compensate yield due to significantly higher plant population in the later case. Among fertility levels, similar seed cotton yield was recorded with the application of 100% RDF (2204 kg ha-1) and 125 % RDF (2295 kg ha-1) but both were significantly better than that of 75 % RDF (1865 kg ha-1) and plant geometry 90 x 45 cm seemed to be ideal for Bt cotton hybrid for realizing higher productivity under the specific agro climatic zone IV b of (Rajasthan).

Volume: 8 | Issue no: 1-2017 | Pagination: 75-79
A field experiment was conducted on loamy sand soil of Agronomy Instructional Farm, Department of Agronomy, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during the Rabi seasons of 2012-13 and 2013-14 to study Rabi fennel (Foeniculum vulgare Mill.) based intercropping systems under different row spacing. The soil of the experimental plot was low in organic carbon and available nitrogen, medium in available phosphorus and potash. The experiment was laid out in split plot design with three replications. Twenty four treatment combinations comprised of four row spacing viz., S1 : (45 cm), S2 : (60 cm), S3 : (75 cm) and S4 : (90 cm) and six intercropping systems treatment viz., IC1 : Fennel sole, IC2 : Fennel + carrot (1:1), IC3 : Fennel + cabbage (1:1), IC4 : Fennel + cauliflower (1:1), IC5 : Fennel + radish (1:1) and IC6 : Fennel + vegetable fenugreek (1:1) were evaluated. The highest seed and straw yields were recorded when the crop was sown at 60 cm row spacing while the lowest seed yield was obtained with the narrow row spacing i.e., 45 cm and straw yield was found with wider row spacing i.e., 90 cm. However, volatile oil and protein yields differed significantly. Significantly higher volatile oil and protein yields were recorded under 60 cm row spacing. Seed and straw yields were recorded significantly the highest with fennel sole as compared to intercropping systems. However, volatile oil and protein yields were recorded significantly the highest with sole fennel. Available nitrogen and phosphorus secured significantly higher values with fennel + vegetable fenugreek (1:1).

Volume: 8 | Issue no: 1-2017 | Pagination: 70-74
An experiment was conducted under protected condition to study the effect of foliar application of GA3 (100 and 150 ppm), urea (1.0 and 1.5 %) and ZnSO4 (0.5 and 1.0 %) on growth and yield of strawberry (Fragaria x ananassa Duch.) cv. SWEET CHARLIE. The results revealed that the applications of GA3 at 150 ppm significantly influenced the growth related parameters viz., highest plant height (18.34 cm), maximum numbers of runners/plant (10.31), highest length of runners/plant (39.76 cm) and maximum number of leaves/plant (36.70) whereas, GA3 at 100ppm significant effect on flowering parameters viz., minimum days to flowering (71.55), maximum number of flowers per plant (19.77) and maximum fruit set/plant (91.80 %) and yield parameters like, maximum number of fruit per plant (18.15), highest yield/plant was 0.17 kg and yield/plot was 4.19 kg. Therefore, from present investigation it can be emphasized that high concentration of GA3 promote vegetative growth and moderate concentration significantly controls flowering and yield attributes in case of strawberry.

Volume: 8 | Issue no: 1-2017 | Pagination: 66-69
This study was carried out to develop best suitable plant population of two safflower cultivars in rainfed condition. The experiment was conducted at Oilseeds Research Unit Dr. P. D. K. V, Akola, during 2015-16 using a FactorialRandomized BlockDesign with three replications. Plant population were 1.66, 1.11, 0.83, 0.66 and 0.55 lakh plants/ha and cultivars included were Annigeri-1 and NARI 38. Branches per plant, effective capsules per plant, 100 seed weight and harvest index were significantly decreased as plant population increased. With increasing plant population, seed yield and biological yield were increased. The highest seed yield was obtained from plant population 1.66 lakh/ha (1150 kg/ha) which was at par with 1.11 lakh/ha plant population (1121 kg/ha) and lowest seed yield was recorded in 0.55 lakh/ha plant population (916 kg/ha). National check Annigeri-1 yielded higher seed yield than NARI- 38 mainly due to higher number of effective capsules per plant. Similar trend was noticed in gross return, net return and B:C
