4. Achievements, Recommendations and Findings:

1993-2000

1. Survey of salt affected soils and quality of irrigation water:

Soil salinity and poor quality of irrigation water have been found to be two most important constraints affecting the optimum production of crops. For assessing type of salt affected soils and quality of irrigation water 819 representative soil samples and 181 irrigation water samples have been analysed, 66.1% soil samples were found to be salt affected which were classified into following categories:

Saline- 43.5%; Saline sodic- 9.8 % and Sodic soils- 12.8%. This study is useful in salt affected soils. Gypsum requirement was worked out for saline sodic and sodic soils.

80.2% irrigation water was of poor quality which were classified as follow:-

Saline- 49.2%; Saline Sodic- 26.7% and Sodic 4.3%. 8.3% of irrigation water had high RSC ( > 5 me/l) values.

Suitable technology for managing poor quality irrigation water is being worked out.

Soil Fertility: Judicious use of fertilizers based on soil testing is one of the most important factor governing productivity of soils. Analysis of 819 soil samples for available N,P and K revealed that 85.8% soils were low in available N whereas 14.2% medium in it. Available P was low in 19.0%, medium in 39.7%  and high in 41.3%. Available K2O was high in 84.5% of the samples whereas 15.5% contained medium range.

Available Micronutrient:         117 representative soil samples were analyzed for DTPA extractable 10.2% samples were deficient (< 0.60 ppm) in available zinc, 38.4% marginal (0.60-1.20 ppm) and remaining 51.8% sufficient in it. Deficiency has been further confirmed by the soil test crop response studies with wheat as a test crop as reported in the section on nutrient management in saline soils.

3. For mustard crop grown under unirrigated heavy texture soils application of 40 Kg N and 40 Kg S ha-1 (through gypsum) was found optimum.

4. For mustard crop 45 cm. spacing between row to row has been found optimum under tank bed, heavy texture soils.

5. The spray of Thio urea @ 0.1% at 60 DAS increases the seed yield of mustard by 10 to 12% over control. In this way an additional return of about Rs.3024 ha-1 can be fetched.

6. The application of Zinc Sulphate @ 20 Kg ha-1 significantly increases the grain yield of lentil.

7.  Mixed cropping of lentil + mustard (12:2 or 6:1 rows) was found superior over lentil alone or over farmers practice (seed mixture).

8. Research conducted to find out the response of sulphur under tank bed micro farming situation revealed that increasing levels of sulphur, significantly increased the grain yield of cluster bean upto 40 kg S/ ha-1, beyond which no further response was observed.

9. Wheat (Raj 1482) irrigated with saline sodic water (EC : 10.4 dsm-1 and SAR : 10.6 ) responded significantly to N, P and Zn. Combined application of 120, 60 and 40 Kg/ ha of N, P2O5 and ZnSO4, respectively increase the grained yield of wheat by 14.0 % over control (90Kg N + 40Kg P2O5  ). It suggests that under saline conditions N, P and Zn requirement is higher as compared to non saline conditions.

10. The optimum seed rate for Gram semi bold varieties was found 80 Kg ha-1 and for small seeded varieties was found 60 Kg ha-1.

Chickpea RSG-44 cultivar is better under tank bed farming situation and seed rate all ready recommended as per D.R. 70 Kg/ha seed rate is confirmed.

3. Adoptability of spices – It was found that Fenugreek, coriander and fennel crops were suitable for cultivation to the Zone. Fenugugreek, Var. RMt-1 with average yield of 25 q per ha was economically suitable for cultivation in Zone IIIb. Likewise, fennel Var-RF-125 (20 q/ha) and coriander RCr 41(15 q/ha) were also suitable for cultivation. Looking to the economics of the species, the Fenugreek, crop was found most economic by providing Rs.40000 per ha, net profit followed by fennel Rs.35000 per ha and crop coriander Rs.30000 per ha net profit.

Experiment conducted to work out the agrotechniques to mitigate the adverse effect of crust formation due to post sowing rains revealed a significant improvement in seed yield due to application of FYM @ 5 tons/ha over furrow and gave 53%, 40%, 60% and 52% higher yield than farmers practice (Broad casting method) in kharif 2000, 2002, 2003 and pooled average, respectively. Application of starch polymer @ 10 Kg/ha (seed mixed) gave better results during kh. 2002 (drought seasons).

The result showed that 1000 ppm Thiourea spray at 50% flowering (75 DAS) produced the maximum seed yield with mean yield of 1108 kg ha-1. It is quite evident from the table that spray of Thiourea found significantly superior over control & all other agrochemicals, but there was no significant effect of spray stage and dose too, but the highest net additional return of Rs. 2955 ha-1 fetched with the 1000ppm of TU at 50% flowering (75 DAS) closely followed by 1000 ppm spray of TU at pre flowering (60 DAS) by giving that additional return of Rs.2845 ha-1

Highest lentil grain yield was recorded with the treatment 40 P2O5 ha-1 through DAP+ PSB closely followed by 40 P2O5 ha-1 through DAP +  PSF. Among the sources of phosphorus DAP found superior over Rock phosphate but there was no significant difference among them, whereas PSB, found superior over PSF. The increase in grain yield was 40.53%, 38.26% and 28.95% by 40 Kg. P2O5 ha-1 through DAP, 40 Kg. P2O5 ha-1 through DAP + PSF and 40 Kg. P2O5 ha-1 through DAP over control. The combined effect of DAP with PSB at 40 P2O5 ha-1 showed maximum positive effect.
