This study has accessed the economic impact of Sub-Surface Drainage (SSD) technology on sugarcane production. The 'with' and 'without' approach was adopted for the collection and analysis of data. 60 sample farmers ‘with SSD’ and 60 sample farmers ‘without SSD’ consisting of total 120 farmers were selected from three tahsils of Sangli district of Maharashtra. The average per hectare establishment cost of SSD system was observed to be Rs. 1,38,183. The per quintal cost of production for adsali sugarcane for with and without SSD farms was Rs. 219 and 279 respectively. The gross return of adsali sugarcane was observed to be 40.77 per cent more on ‘with SSD’ farms as compare to the ‘without SSD’ farms of adsali sugarcane. The per quintal cost reduction for adsali sugarcane observed to be 27.43 per cent on ‘with SSD’ farms over the ‘without SSD’ farms. The per farm gross income accrued from cultivation of adsali sugarcane was Rs. 414675.25 and Rs. 245619.15 on farms with and without SSD, respectively showed an increase of 40.77 per cent in gross returns due to the adoption of SSD technology. While, the farm business income, family labour income, net income were also higher on farms with SSD over the farms without SSD with the tune of 67.98, 86.65and 104.44 per cent, respectively.
Seed pelleting is the process in which inert materials are added to seed with an objective to improve seed placement, germination and crop stand and to reduce seed rate and to impart protection against various biotic and abiotic stresses specially in case of pulses as few of them have very small seeds which are difficult to handle otherwise. In present scenario pulses are proving to be an essential immunity booster as they are rich source of proteins and other essential nutrients. In Indian prospects the major constraints in pulse production are their low production and productivity. Thus, seed pelleting has vast potential to overcome these issues because of above stated advantages.
The growth of the Scenedesmus spinosus microalgae was evaluated in four culture mediums: Z8, Watanabe, Bristol and BG-11, using a pilot raceway photobioreactor. The reactor used had a culture volume of 1.2 m3, it was built of fiberglass and covered with a transparent polycarbonate lid on top to avoid contamination. Turbidity, total solids, solar irradiation, and temperature were measured for a period of 28 days. Biomass growth was evaluated through the change in turbidity over time and gravimetry tests, for the four analyzed culture mediums. The culture medium showing the highest biomass yield over the time corresponded to the Z8 medium, closely followed by Watanabe, while Bristol and BG-11 generated the lowest biomass increment. The highest productivity value corresponded to 55.7 g m-3d-1 with Z8 medium while the lower biomass productivity figure corresponded to 5.6 g m-3d-1 with Bristol medium.
Mango leaf cutting weevil is the important serious pest of mango in sub-Himalayan Terai region of West Bengal. The incidence of leaf cutting weevil was recorded on rejuvenated plants of different mango cultivars Amrapali, Mallika, Himsagar, Fazli and Langra after the emergence of new leaves. The leaf cutting weevil incidence were correlated with different weather parameters like maximum and minimum temperature, relative humidity and rainfall. Among the all-weather parameters the leaf cutting weevil maximum incidence positively correlated with minimum temperature in cvs. Mallika (r = 0.803*) and Langra (r ꞊ 0.720*). In Amrapali the highest incidence was correlated with maximum relative humidity (r ꞊ 0.660*), Fazli (r ꞊ 0.652*) and Himsagar (r ꞊ 0.643*) the maximum incidence was correlated with minimum temperature and maximum relative humidity. Stepwise regression equation was developed to predict the infestation of leaf cutting weevil on rejuvenated mango cultivars as affected by the prevailing weather parameters like temperature, relative humidity and rainfall were considered for individual variables for regression analysis. Maximum regression coefficient (R2 = 0.703) was recorded in Mallika followed by Amrapali (R2 = 0.629), whereas, the minimum value was recorded in Himsagar (R2 = 0.488).
A field experiment was conducted at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal during Rabi 2018 to study the nitrogen dynamics in organically cultivated paddy soils of coastal cauvery deltaic region. This study was conducted to evaluate the extent of nitrogen contribution and their dynamics in soil by added organics like green manures (Daincha and sun hemp) and green leaf manures (Pungam and gliricidia) with different levels of vermicompost Viz., 0 t ha-1, 1 t ha-1 and 2 t ha-1. The mineralization pattern of nitrogen is NH4 - N and NO3 - N. During decomposition, before transplanting, after transplanting in early and later stages noted a gradual increase in nitrogen release but steady release observed during mid-stages. In terms of losses, the control registered significantly higher volatilization loss of 1.99 Kg N ha-1 week-1 during second week after transplanting. While the organic treatments registered significantly higher volatilization loss during 13th and 14th week after transplanting. Similarly, the control plot registered significantly higher loss of NO3 - N (2.25 Kg ha-1 week-1) during the 1st week after transplanting and the organic manures showed higher NO3- N loss during 5th to 9th week after transplanting. The total weed removal of nitrogen ranging from 1.8 to 2.6 kg N ha-1. In total, the losses of N from rice soil including crop uptake ranged from 94.6 kg ha-1 in absolute control to 147.2 kg ha-1 in daincha treated plot. As well as, the daincha treated plot resulted a net gain of + 9.6 kg N ha-1 among other green manure / green leaf manure treatments. Among the different vermicompost treatments, application of vermicompost at 2 t ha-1 resulted a net gain of + 4.4 kg N ha-1. From the above observations, it could be concluded that, application of daincha is found to be a suitable green manure for rice crop. Which helps to synchronize and release the nitrogen as per the demand of rice crop.
